21 free tools for merging, splitting, compressing, and converting PDF files — including Word, Excel, PowerPoint, and image conversion.
PDF files are everywhere, but editing them usually means either paying for a subscription or trusting an unfamiliar website with a document you'd rather not upload anywhere. This collection covers the PDF tasks people need most — combining files, extracting pages, compressing for email, adding page numbers or a watermark — plus conversion to and from Microsoft Word and Excel, all running entirely in your browser using open, well-established JavaScript libraries.
Because everything happens locally on your device, these tools are safe to use even on confidential or sensitive documents — contracts, financial records, personal paperwork — since nothing is ever uploaded to a server in the process.
